Phalaenopsis leaves turn yellow for three reasons. First, if the light is too strong, the leaves will be sunburned if they are exposed to the sun for a long time. It is necessary to reduce the exposure time, reduce the light intensity, and slowly recover.
The second is the lack of water. It likes a humid environment. If the environment or soil is too dry, it is prone to dry yellow. It needs to be supplemented with water. Third, the root system is rotten. If the root system is rotten, the leaves will turn yellow. The rotten roots should be trimmed, disinfected and then replanted.
1. the light is too strong
Reason: Light is very important for its growth. But if you leave it in the sun for a long time, the plant will be sunburned. Because the light is too strong, the water on the leaves evaporates too quickly, resulting in the phenomenon of yellow leaves.
Solution: If it is yellowed, be sure to control the light. Reduce sun exposure and reduce light intensity. It should be blocked at noon and in the strong light of summer, and the plants should be moved to a place with astigmatism, and they will recover after a period of maintenance.
2. Lack of moisture
Reason: Phalaenopsis likes a slightly humid environment and is not drought tolerant. If the air humidity is too low and the soil is too dry, the leaves will slowly turn yellow, which is the common dry yellow situation, and the leaves will gradually thin.
Solution: If it is caused by dry yellow, the yellow leaves should be cut off. It is also necessary to add water, water as soon as possible to make the soil moist, and strengthen ventilation after watering, so as to alleviate the phenomenon of yellow leaves.
3. Root rot
Reason: The yellowing of its leaves is most likely because the root system is rotten. Once the roots are rotten, the leaves will become soft, droopy and yellow. The roots cannot absorb nutrients, and the leaves will turn yellow due to lack of nutrients.
Solution: If the root system is rotten, remove the pot and prune the rotten roots. After pruning, it should be disinfected, and the wound should be dried and replaced with new soil to replant. In addition, we should pay attention to preventive work in the later stage, use soil with good drainage performance, and water in moderation to avoid root rot.
